Summary: | To provide: a rotator capable of easily generating a phase difference between a plurality of iron core blocks in an assembly step, and suppressing deviation of an iron core unit against a rotational shaft in a peripheral direction during operation; and a dynamo-electric machine.SOLUTION: A rotator comprises: a rotational shaft; and a plurality of iron core blocks supported by the rotational shaft. The rotational shaft contains a plurality of tooth parts arranged in a peripheral direction. Each of the iron core blocks includes multiple concave parts which are engaged with the tooth parts. The plurality of iron core blocks is spline-coupled to the rotational shaft in a state where a phase of each of a plurality of S pole magnets of one adjacent iron core block is deviated so as to overlap an N pole magnet and a peripheral direction of any of the other adjacent iron core blocks.SELECTED DRAWING: Figure 2
【課題】複数の鉄心ブロックの間における位相差を組立工程において容易に生じさせることができると共に、動作中に鉄心ユニットが回転軸に対して周方向にずれるのを抑制できる回転子、および、回転電気機械を提供する。【解決手段】回転子は、回転軸と回転軸によって支持される複数の鉄心ブロックとを備える。回転軸は、周方向に並ぶ複数の歯部を含む。複数の鉄心ブロックの各々は、複数の歯部とそれぞれ噛み合う複数の凹部を含む。複数の鉄心ブロックは、隣接する一方の鉄心ブロックの複数のS極磁石の各々が隣接する他方の鉄心ブロックのいずれかのN極磁石と周方向に重なるように互いに位相がずらされた状態で、回転軸にスプライン結合されている。【選択図】図2 |
